It is a lightweight like the Goldcrest which, however, unlike ist more robust twin species, mostly leaves Switzerland in the winter. It is less bound to spruce forests than the Goldcrest and in addition to coniferous trees also uses deciduous ones. Where forests are damaged, the birds soon have problems: The thinned out branches no longer provide sufficient shelter and the food supply is severely restricted.
